When the sprinkler is running, the cam rotates slowly -- at roughly 1 revolution per minute (rpm) -- this is what causes the arm to oscillate back and forth. There is also the spray arm itself, which is a hollow aluminum tube with holes in it (on some sprinklers there are nozzles on this tube):
What is the spray arm on a sprinkler?
The spray arm has a ferrule and an O-ring seal on it, and it screws into the body of the sprinkler. You can see that this is an incredibly simple device at its core. Water flows into the spray arm -- the aluminum tube -- and it sprays out through the holes or nozzles. The cam pushes the spray arm back and forth.
How does a sprinkler work?
Many different types of sprinklers use water power in the same way. Some are jet-powered rather than turbine-powered, but they are all using the force of moving water to create linear or rotational motion. In theory, you could create a little water-turbine electrical generator and attach it to your hose to create several watts of power -- you could power a flashlight bulb while you water your lawn at night!
